Abstract:
We present new BVRI broadband photometry for the old open cluster NGC
188, based on an analysis of 299 CCD images either obtained by us,
donated by colleagues, or retrieved from public archives.
Description:
We obtained 86 CCD images of NGC 188 with the f/5 Newtonian camera on
the Plaskett 1.8m telescope of the Dominion Astrophysical Observatory
(DAO) on the nights of 1996 July 11 and 12 (UT).
